Buying gold jewelry is a big decision for most families in Tamil Nadu. Gold is not only a fashion choice but also a long-term asset. Because gold prices are high and fake jewelry is common in the market, checking gold purity before buying is very important.
This guide explains how you can verify 916 BIS Hallmarked gold and avoid being cheated. This blog is written to help buyers choose safe and certified jewelry from trusted stores like Eswari Jewelers .
Why Gold Purity Matters
Gold purity tells you how much real gold is present in a jewelry piece. Higher purity means higher value, a better resale price, and more trust in what you are buying. Pure gold keeps its worth over time, so it is safer for long-term savings and family use.
Jewelry with correct purity does not lose color quickly and is less likely to cause skin problems. It also helps you get a fair price when you exchange or sell the jewelry in the future. If purity is low or not certified, you may pay more for less gold without knowing it.
That is why checking gold purity before buying is important. It protects your money, ensures quality, and gives peace of mind that your jewelry is genuine and valuable.
What is BIS Hallmark?

BIS Hallmark is an official certification issued by the Bureau of Indian Standards (BIS) , the national standards body of India. It confirms that the gold jewelery has been tested and certified for purity in a government-approved hallmarking center.
When a piece of jewelery carries a BIS Hallmark, it means:
- The gold is genuine
- The purity level has been accurately tested
- The jewelery meets Indian quality standards
- The buyer is legally protected against incorrect purity claims
BIS hallmarking brings transparency and trust to gold buying. It ensures that customers get the purity they are paying for and reduces the risk of fraud or misrepresentation.
For this reason, always choose BIS Hallmarked gold jewelry when purchasing gold in Tamil Nadu to ensure quality, safety, and long-term value.
What Is 916 Hallmark Gold?
916 gold means the jewelry contains 91.6% pure gold . This is also called 22-carat gold .
Common gold purity levels:
- 24K = 999 (99.9% pure gold)
- 22K = 916 (used for jewelry)
- 18K = 750 (used for diamond jewelry)
That is why most jewelry in India is made using 916 hallmark gold . It is strong and suitable for daily wear and weddings.

Why Hallmarked Jewellery Is Important
Hallmarked jewellery gives you confidence that you are paying for real gold and the correct purity. When a piece carries the BIS hallmark, it means the gold has been tested and certified by an authorized laboratory. This protects buyers from being cheated and ensures long-term value.
Hallmarked jewellery offers many benefits:
- It gives the correct value for the price you pay.
- It is easy to resell or exchange in the future.
- It protects you from fraud and low-quality gold.
- It keeps your family’s investment safe for the long term.
On the other hand, buying non-hallmarked jewellery can be risky. Since there is no official certification, you cannot be fully sure about the gold content.
Non-hallmarked jewellery may:
- Contain less gold than promised.
- Be difficult to resell, especially at branded stores.
Offer no proof of purity, which reduces trust and value.
For these reasons, it is always safer and smarter to choose BIS-certified gold jewellery when buying ornaments for weddings, festivals, or long-term savings.
